Amid a flurry of new construction at SpaceX’s Boca Chica facilities, technicians have begun to install thruster pods on Starhopper in anticipation of the prototype’s first untethered flights.

According to CEO Elon Musk, Starhopper’s “untethered hover tests” will begin with just one Raptor engine installed, potentially allowing hops to restart within the next few weeks. SpaceX is currently testing Raptor SN03 (and possibly SN02) a few hundred miles north in McGregor, Texas, just a few hours’ drive south once the engine is deemed flight-ready. Meanwhile, Starhopper itself needs a considerable amount of new hardware before it can begin Raptor-powered flight testing.

A Falcon Raptor-powered Starship

Purely from a visible perspective, the most important component Starhopper is missing is a way to control its attitude and remain stable while under Raptor power, particularly critical for hovering. Enter the aptly-named attitude control system (ACS), essentially a pod of omnidirectional thrusters. SpaceX already happens to have its own extremely mature ACS proven over nearly two dozen successful Falcon 9 and Heavy booster landings, as well as every Falcon upper stage that has ever flown. SpaceX’s ACS is based on powerful nitrogen gas thrusters, known for their white puffs during Falcon 9 booster recovery and landing operations.

On May 6th and 7th, SpaceX began to install what looked like Falcon ACS pods on Starhopper. Curiously, of the two pairs of thrusters now installed, half appear to be taken directly off of older mothballed Falcon 9 boosters, while the other two seem to have been acquired from a Falcon 9 Block 5 rocket. The latter pods may very well have come from Falcon 9 B1050, the booster that unintentionally landed in the Atlantic Ocean last December.

Based on the asymmetric location of the first two pod groups, Starhopper’s ACS will probably use a tripod layout. Additionally, the reason for the thruster pairs – versus Falcon 9’s single pods – is likely simple: Starhopper is far heavier than a Falcon booster. To get the same level of control authority, SpaceX is thus pairing pods together to double the functional strength of Starhopper’s ACS.

This leads smoothly to the installation of two (likely soon to be three) new composite-overwrapped pressure vessels (COPVs). Starhopper already has two COPVs installed on the outside of its upper tank dome, now effectively confirmed to be helium containers needed to pressurize the vehicle’s methane and oxygen tanks. Based on the fact that Starhopper’s new ACS pods appear to have come straight from Falcon boosters, it’s safe to say that the 2 (or 3) new COPVs will supply the hopper’s thrusters with gaseous nitrogen.

The Ugly Starshipling

In general, this is just the latest chapter in the book of the oddity that is Starhopper. With helium tank pressurization and nitrogen ACS thrusters taken straight from Falcon 9, a major facet of SpaceX’s Mars architecture is entirely missing from the prototype. Known as autogenous pressurization, BFR was meant to use gasified versions of its onboard liquid oxygen and methane to pressurize its propellant tanks. In a similar vein, BFR was expected to integrated the same propellant into its ACS. Simply put, helium is simply out of the question if SpaceX wants to realize its reusable Mars transport architecture. Mars does have a minute quantity of nitrogen available in its already very thin atmosphere, but extracting hundreds or thousands of kilograms is impractical in the near-term, particularly if the first Starship have to carry all of their extraction equipment from Earth.

In January, Musk noted that methane/oxygen RCS thrusters were no longer baselined on Starship/Super Heavy. It’s unclear if the “cold gas” referred to will be nitrogen on the final design.

Although Musk has seemingly confirmed that Starship and Super Heavy will use ACS thrusters more akin to the Falcon family’s cold nitrogen gas pods, he did also confirm that autogenous pressurization would be a part of even the earliest iterations of the rocket. The move from carbon fiber to steel tanks likely made a major difference, as carbon composites have extremely limited heat resistance.

Without autogenous pressurization and propellant tanks closer to the thickness of orbit-capable Starships, Starhopper is really more of a mobile test stand for Raptor than anything else. The ungainly vehicle also offers SpaceX engineers an opportunity to test Starship/Super Heavy avionics in flight conditions, particularly with respect to controlling a real Raptor engine on the fly.

Pending the arrival and installation of its lone Raptor engine, Starhopper will likely be ready to return to hop testing before the end of May. (NASASpaceflight – bocachicagal)

Tesla lands massive deal to expand charging for heavy-duty electric trucks

Tesla has landed a massive deal to expand its charging infrastructure for heavy-duty electric trucks — and not just theirs, but all manufacturers.

Tesla entered an agreement with Pilot Travel Centers, the largest operator of travel centers in the United States. Tesla’s Semi Chargers, which are used to charge Class 8 electric trucks, will be responsible for providing energy to various vehicles from a variety of manufacturers.

The first sites are expected to open later this Summer, and will be built at select locations along I-5 and I-10, major routes for commercial vehicles and significant logistics companies. The chargers will be available in California, Georgia, Nevada, New Mexico, and Texas.

Each station will have between four and eight chargers, delivering up to 1.2 megawatts of power at each stall.

The project is the latest in Tesla’s plans to expand Semi Charging availability. The effort is being put forth to create more opportunities for the development of sustainable logistics.

Senior Vice President of Alternative Fuels at Pilot, Shannon Sturgil, said:

“Helping to shape the future of energy is a strategic pillar in meeting the needs of our guests and the North American transportation industry. Heavy-duty charging is yet another extension of our exploration into alternative fuel offerings, and we’re happy to partner with a leader in the space that provides turnkey solutions and deploys them quickly.”

Tesla currently has 46 public Semi Charger sites in progress or planned across the United States, mostly positioned along major trucking routes and industrial areas. Perhaps the biggest bottleneck with owning an EV early on was charging availability, and that is no different with electric Class 8 trucks. They simply need an area to charge.

Tesla is spearheading the effort to expand Semicharging availability, and the latest partnership with Pilot shows the company has allies in the program.

The company plans to build 50,000 units of the Tesla Semi in the coming years, and with early adopters like PepsiCo, DHL, and others already contributing millions of miles of data, fleets are going to need reliable public charging.

Tesla is partnering with other companies for the development of the Semi program, most notably, a conglomeration with Uber was announced last year.

The ride-sharing platform plans to launch the Dedicated EV Fleet Accelerator Program, which it calls a “first-of-its-kind buyer’s program designed to make electric freight more affordable and accessible by addressing key adoption barriers.”

The Semi is one of several projects that will take Tesla into a completely different realm. Along with Optimus and its growing Energy division, the Semi will expand Tesla to new heights, and its prioritization of charging infrastructure.

Elon Musk’s tunneling startup, The Boring Company, has welcomed its newest Vegas Loop station at the Fontainebleau Las Vegas.

The Fontainebleau is the latest resort on the Las Vegas Strip to embrace the tunneling startup’s underground transportation system.

Fontainebleau Loop station

The new Vegas Loop station is located on level V-1 of the Fontainebleau’s south valet area, as noted in a report from the Las Vegas Review-Journal. According to the resort, guests will be able to travel free of charge to the stations serving the Las Vegas Convention Center, as well as to Loop stations in Encore and Westgate.

The Fontainebleau station connects to the Riviera Station, which is located in the northwest parking lot of the convention center’s West Hall. From there, passengers will be able to access the greater Vegas Loop.

Vegas Loop expansion

In December, The Boring Company began offering Vegas Loop rides to and from Harry Reid International Airport. Those trips include a limited above-ground segment, following approval from the Nevada Transportation Authority to allow surface street travel tied to Loop operations.

Under the approval, airport rides are limited to no more than four miles of surface street travel, and each trip must include a tunnel segment. The Vegas Loop currently includes more than 10 miles of tunnels. From this number, about four miles of tunnels are operational.

The Boring Company President Steve Davis previously told the Review-Journal that the University Center Loop segment, which is currently under construction, is expected to open in the first quarter of 2026. That extension would allow Loop vehicles to travel beneath Paradise Road between the convention center and the airport, with a planned station located just north of Tropicana Avenue.

Tesla has expanded its footprint near its Fremont Factory by leasing a 108,000-square-foot R&D facility in the East Bay. 

The lease adds to Tesla’s presence near its primary California manufacturing hub as the company continues investing in autonomy and artificial intelligence.

A new Fremont lease

Tesla will occupy the entire building at 45401 Research Ave. in Fremont, as per real estate services firm Colliers. The transaction stands as the second-largest R&D lease of the fourth quarter, trailing only a roughly 115,000-square-foot transaction by Figure AI in San Jose.

As noted in a Silicon Valley Business Journal report, Tesla’s new Fremont lease was completed with landlord Lincoln Property Co., which owns the facility. Colliers stated that Tesla’s Fremont expansion reflects continued demand from established technology companies that are seeking space for engineering, testing, and specialized manufacturing.

Tesla has not disclosed which of its business units will be occupying the building, though Colliers has described the property as suitable for office and R&D functions. Tesla has not issued a comment about its new Fremont lease as of writing.

AI investments

Silicon Valley remains a key region for automakers as vehicles increasingly rely on software, artificial intelligence, and advanced electronics. Erin Keating, senior director of economics and industry insights at Cox Automotive, has stated that Tesla is among the most aggressive auto companies when it comes to software-driven vehicle development.

Other automakers have also expanded their presence in the area. Rivian operates an autonomy and core technology hub in Palo Alto, while GM maintains an AI center of excellence in Mountain View. Toyota is also relocating its software and autonomy unit to a newly upgraded property in Santa Clara.

Despite these expansions, Colliers has noted that Silicon Valley posted nearly 444,000 square feet of net occupancy losses in Q4 2025, pushing overall vacancy to 11.2%.
